The Solaris group is a forum where peers share technical expertise, solve problems, and discuss issues related to the Solaris operating system, including OS-related malfunctions, security issues, and network performance.

You can run Solaris x86 and start SUN Cluster software. But this will be HA solution. If you search something like load balancing, cloud, etc search for other solution
P.S. If you by mistake post your question in Solaris group better report in in appropriate group
